Quite simply, it tells me you are an adult, probably out of school and in the workforce, unless you are working towards an advanced degree, or have some other reason for still being in school. (I can think of several good reasons to still be in school at 23. It's just not common.)
In any case, you probably have at least some experience with what life is really like, outside the academic classroom. Taken in conjunction with your location, I make the (possibly faulty) assumption that you have traveled, at least a little within Turkey, and very probably within Europe. (I also take into consideration a poster's understanding of the topic of the thread, or at least the situation being discussed. Being familiar with multiple cultures isn't required, but it rarely hurts.
)
Now that I've probably guessed everything wrong about you,
let me say that I use age as a guide primarily when the poster makes some outrageous statement. If he's 13, I'll probably just dismiss him as a silly kid who doesn't know any better, whereas if he's an adult, I may question what planet he lives on.
Anyway, it's just one guide, one clue as to where the poster is coming from. There are many other factors that come into play, including nationality, special knowledge, posting history, etc.
